Rupture disc

Abstract

A rupture disc of a thermoplastic material in which metal wires or carbon fibers are imbedded. According to a particular embodiment of the invention, at least one of the wires is designed as an electrical conductor through which current flows.

I claim: 
     
       1. A rupture disc of thermoplastic material, having a plurality of metal wires or carbon fibers running parallel to a surface of said disc embedded in said thermoplastic material. 
     
     
       2. The disc of claim 1 wherein at least one of said wires is an electric conductor through which current flows. 
     
     
       3. The disc of claim 1 wherein said thermoplastic material is selected from the group consisting of polyethylenes, polypropylenes, polyamides, polyvinyls, polyacetates, polyesters, polytetrafluoroethylenes, silicone rubbers, and mixtures thereof. 
     
     
       4. The discs of claim 1 wherein said thermoplastic material is selected from the group consisting of polyethylenes, polyamides, polytetrafluoroethylenes, and mixtures thereof. 
     
     
       5. The disc of claim 1 wherein said metal wires are of a metal selected from the group consisting of iron, aluminum, copper, silver, and alloys thereof. 
     
     
       6. The disc of claim 1 wherein said metal wires are composed of copper or iron. 
     
     
       7. The disc of claim 1 wherein said metal wires are grid or mesh. 
     
     
       8. The disc of claim 1 wherein said carbon fibers are a woven fabric or felt. 
     
     
       9. The disc of claim 1 further comprising a plurality of layers. 
     
     
       10. The disc of claim 1 wherein said wires or fibers are parallel to each other.
